The most canonical way is to use the boundary data inside OSM. This is usually stored in a relation tagged with the key "admin_level" and values from "2" (for countries) to "10" (for parts of hamlets, depending on the country) which countains all the ways that constitute the boundary. The data is of quite good quality for a lot of cities in various European countries but it is poor for the most country boundaries themselves (there are gaps in the boundaries). But this should improve over the time. I'm currently working as part of a larger project on this service. The reverse gazetteer itself based purely on OSM data works fine, but it is not online yet. Currently, I'm working on making minute updates possible. And the entire system should anyway be re-tested after the move to the 0.6 api which will take place at 20th april. So I think I'll probably go online around mid-may. I you can't wait, I can put the source code on the web, but it is really a huge mess at the moment.
